I then did x(x+y)-2(x+y)
then (x-2) (x+y)....is this my final answer? That is the question...I have factored it this far...should I go further?
Factor x^2+xy-2x-2y?

That's as far as you need to go.

That is exactly right. You shouldn't go further....because you can't. (x - 2) (x + y) is fully factored.

x(x+y)-2(x+y)=(x+y)(x-2)

that's as far as you can factor unless you wanna redo the whole thing lol

No, you are done. Nice job.

x^2 + xy - 2x - 2y
= (x^2 + xy) - (2x + 2y)
= x(x + y) - 2(x + y)
= (x + y)(x - 2)
= (x^2 + xy) - (2x + 2y)
= x(x + y) - 2(x + y)
= (x + y)(x - 2)
